The Lights of Shantinagar is a warm and lively portrait of family life set in modern India where new philosophies are reshaping old traditions and one woman's astute observations can change everything.

Aspiring quantum physicist Sumi is newly married and has moved into her husband's family home. Here she observes that the beguilingly tranquil middle-class town of Shantinagar is not very different from her beloved quantum world: the happenings in one house are cryptically entangled with things next door, objects mysteriously disappear and unexpected interactions reveal surprising truths.

As the line between right and wrong begins to blur, new discoveries force the residents of Shantinagar to reflect on what they truly know about themselves and the ones they love. Meanwhile, Sumi must blend logic with love to make sense of her new circumstances.
